Cannot be built with the current version of libtomcrypt (from Git)

Probably, some structures are changed.

In file included from tlssimple.c:11:

There are some warnings too.

Let me check. Thank you for reporting.

I think you are right, but in libtomcrypt releases, we have:

/** An ECC key */
typedef struct {
    /** Type of key, PK_PRIVATE or PK_PUBLIC */
    int type;

    /** Index into the ltc_ecc_sets[] for the parameters of this curve; if -1, then this key is using user supplied curve in dp */
    int idx;

    /** pointer to domain parameters; either points to NIST curves (identified by idx >= 0) or user supplied curve */
    const ltc_ecc_set_type *dp;

    /** The public key */
    ecc_point pubkey;

    /** The private key */
    void *k;
} ecc_key;

But indeed, in master branch we have:

/** An ECC key */
typedef struct {
    /** Type of key, PK_PRIVATE or PK_PUBLIC */
    int type;

    /** Structure with domain parameters */
    ltc_ecc_dp dp;

    /** Structure with the public key */
    ecc_point pubkey;

    /** The private key */
    void *k;
} ecc_key;

It should be fairly easy to rewrite this code, but not being an official release, I don't think it is a good ideea to support it. Things may change until the next official release.
